For anyone interested here is a link to 301KAR3.030 that Str8Shooter1 mentioned: http://www.lrc.state.ky.us/kar/301/003/030.htm
My interpretation on this KAR is that hunting at night for coyote is legal as long as you are not using an electronic call. If you use mouth or hand calls you are totally legal to hunt at night.
If you do hunt at night I would print the above KAR and have it in your possession.
It doesn't matter what the hunting manual says as long as you are legal in the eyes of the KRS and KAR. These are the laws the judges use to determine if you were legal or not.
According to the law stated above night hunting for coyotes is legal in Kentucky.
